My first post on the forums, go easy on me...
So I'm getting a feel for the new lab my college has and all of the equipment in it so I thought I'd set up some VERY simple circuits just to get used to some of the DC power sources (there are a few different ones).
No matter what I do though, the current always seems to be slightly HIGHER than the expected value coming from the given voltage and resistance.
For example: I'll set up V = 10v R = 10Ω and get values above the expected (slightly)
I'll hit 1 amp @ 9.8 volts
I hit 1.1 amps @ 10.75 volts
I hit 1.2 amps at 11.7 volts
Any idea what seems to be causing this simulated lower resistance?
